An Al-Mg which is having 0.5 g of alloy in the acid forms the 600mL of H saturated with water vapor at 20°C. PH2O = 18 torr. Where the Barometric pressure was 763 torr.
a. Determine the numbers of mols of H evolved?
b. Determine the numbers of grams of Mg in the alloy?
c. Determine the weight percent of Al in the alloy?
d. Is the partial pressure of the evolved H going to be 763-18=745 torr?
